Aerodynamic beam3 visualization problem

[libo663]

When modeling a twisted blade, the aerodynamic beam3 element was well defined, but in Blendyn it didn't twist as expected.

Hi @libo663, the problem was in how the .log file entry of aerodynamic beam2 and aerodynamic beam3 elements was written (incorrectly) in MBDyn. With this fix the problem should be fixed (test case follows).

c81 data: (integer NACA0012 = 12), "../../var/naca0012.c81";
	set: const real ALPHA = 0.;
	set: const real TWIST075 = 7.*deg2rad;
	aerodynamic beam3: 2, 2,
		reference, node, null,
		reference, node,
			1, 0., cos(ALPHA), sin(ALPHA),
			3, 1., 0., 0.,
		reference, node, null,
		reference, node,
			1, 0., cos(ALPHA), sin(ALPHA),
			3, 1., 0., 0.,
		reference, node, null,
		reference, node,
			1, 0., cos(ALPHA), sin(ALPHA),
			3, 1., 0., 0.,

Hi @zanoni-mbdyn . Thank you for fixing this problem, I will try it later.
